@KemoSace,
You can mainline auto’s in soil but it will cost you a week and if you’re unlucky 2 to 3 weeks. Sometimes it’s worth it , but it mostly isn’t.
@KemoSace, no I don’t always top my autos but since it’s in a hydroponic medium I think it will recover faster from the stresses of a mainline ! I wouldn’t try this in soil but if your plant is healthy and growing fast then why not !
